<h1 class="topictitle1">Step 3: Registering a TDSQL Database</h1>
<div><p>After ProtectAgent is installed on the host where the TDSQL database resides, the <span>OceanProtect</span> automatically discovers the TDSQL database host. Register TDSQL cluster and instances of the host on the management page to protect the database or use the database as the restoration target.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>The <span>OceanProtect</span> can back up non-distributed and distributed instances of a TDSQL database.</p>
</div>
<div class="section"><h4 class="sectiontitle">Prerequisites</h4><ul><li>All cluster nodes of the database must be registered. Data cannot be backed up on unregistered nodes, and as a result, user data at the restoration time point will be inconsistent.</li><li>Before registering a TDSQL instance, ensure that each host in the cluster has been registered.</li></ul>
